It is bright.Moreover, in the explanation after the 2nd embodiment, for the 1st embodiment or other embodiments effect achieved
The identical effect of fruit, the description thereof will be omitted.
[the 1st embodiment]
Fig. 1 is the summary section of the motor 1 of the 1st embodiment of the utility model.
As shown in Figure 1, the motor 1 of present embodiment includes stator 2, with coil (illustration omitted)；And rotor
(illustration omitted) is configured at the inside of the radial DR of stator 2 in a manner of it can rotate.
Stator 2 includes stator core 3, coil (illustration omitted), peripheral members 4, moulded resin portion 5 and the non-transmitting of stress
Portion 6.
Stator core 3 is for example made of the multiple magnetic steel plates being laminated along axial DD.The stator core 3 has cylindric back magnetic
Yoke and from the back magnetic yoke to the inside of radial DR multiple teeth portion outstanding.Coil (illustration omitted) is wound in stator core 3
Each teeth portion of multiple teeth portion.
Peripheral members 4 are, for example, the component of the tubular made by aluminium, ferrous material.The peripheral members 4 are from radial direction DR's
The mode that outside surrounds the back magnetic yoke of stator core 3 configures.Peripheral members 4 are for example fixed on the back magnetic yoke by hot jacket.
Moulded resin portion 5 is in the outer of the axial DD of stator core 3 and the coil (illustration omitted) for being wound in the stator core 3
Side and radially DR accompany the mode of the non-transfer part 6 of stress at it between peripheral members 4, configure the radial direction in peripheral members 4
The inside of DR.The moulded resin portion 5 is being wound with coil (illustration omitted) and is being configured with peripheral members 4 and the non-transfer part of stress
After 6 stator core 3 is packed into mold (illustration omitted), make to flow into made of the liquid resin solidification of the mold.
The non-configuration of transfer part 6 of stress is in stator core 3 and the axial DD for the coil (illustration omitted) for being wound in the stator core 3
Outside and configuration peripheral members 4 radial DR inside.Radially DR is set to moulded resin portion 5 to the non-transfer part 6 of the stress
Between peripheral members 4, make to reduce caused by the contraction because of moulded resin portion 5 to the transmission capacity of the stress of peripheral members 4.Specifically
For, the non-transfer part 6 of stress by peripheral members 4 inner peripheral surface circumferentially DC paste band-like component formed, or by
The inner peripheral surface of the peripheral members 4 cricoid component that circumferentially DC is configured is formed.It (is saved in order to ensure being wound in the coil of stator core 3
Sketch map shows) and peripheral members 4 between insulation, the non-transfer part 6 of the stress is preferably made of insulating materials.
In general, the resin of molded coil is in the state of being tightly attached to peripheral members possessed by stator, and heating makes
What it was solidified to form.Therefore, the resin can cause and peripheral members when returning to room temperature because of the difference of coefficient of thermal expansion
It pulls mutually, makes stator deformability.
On the other hand, using the motor of present embodiment 1, stress is set between moulded resin portion 5 and peripheral members 4
Non- transfer part 6, therefore, become makes the heating of moulded resin portion 5 solid in the state of making moulded resin portion 5 and peripheral members 4 separate
Change.Therefore, moulded resin portion 5 is when returning to room temperature, it is difficult to generate the feelings that peripheral members 4 are pullled because of the difference of coefficient of thermal expansion
Condition is able to suppress the deformation of the stator 2 obtained by molding.

11 is different from the 1st embodiment with non-16 this point of transfer part of stress etc. in the replacement non-transfer part 6 of stress.
In the motor 1 of the 1st embodiment, stress is pullled in the moulded resin portion 5 being heat cured for when returning to room temperature
There is the case where gap is generated between the non-transfer part 6 of stress and peripheral members 4 in non-transfer part 6.In non-6 He of transfer part of stress
Between peripheral members 4 generate gap in the case where, there are moisture etc. from the gap immerse etc. drawbacks.
Here, being used as the non-transfer part 16 of stress, being and the non-biography of stress as shown in Fig. 2, motor 11 includes component 16a
Pass the same component in portion 6；And sealant 16b, with retractility, sealant 16b is clipped in the component 16a and periphery structure
Between part 4.After sealant 16b is coated between component 16a and peripheral members 4, sealant 16b is in 5 quilt of moulded resin portion
It is pullled when being heating and curing and returning to room temperature, but since sealant 16b is relatively thin and easy extension, it can make because of mould
It is reduced caused by the contraction of resin portion 5 processed to the transmission capacity of the stress of peripheral members 4.
Using the motor 11 of present embodiment, it is clipped in sealant 16b between component 16a and peripheral members 4, therefore,
Even if in the case where component 16a is pullled in the moulded resin portion 5 being heat cured for when returning to room temperature, it is also difficult in component 16a
Gap is generated between peripheral members 4, is able to suppress the drawbacks such as moisture immersion.
